2028 Democratic Nominee Odds: Is Newsom the Favorite?

Gavin Newsom is the Kalshi favorite to win the 2028 Democratic nomination, as of the August 9 board below, and the race is nowhere near settled. No name on the 47-candidate board traded above 17 cents. Our seven-model AI panel read the same polls price-blind and picked a different favorite, at triple his market price.

The Quick Answer

Market, as of August 9, 2026: Gavin Newsom leads at 16.5¢, with Jon Ossoff and Alexandria Ocasio-Cortez at 14.5¢ each. Panel blend: Pete Buttigieg is the favorite at 15.8%, a name Kalshi sold for 5.45¢. Every seat priced Buttigieg above the market, and no seat came close to the market on Ossoff.

Can You Buy The Field?

No. Each contract pays if that person accepts the 2028 Democratic nomination, and there is no field contract, so an unlisted nominee means every contract on the board settles NO. The listed midpoints summed to about 102 cents on August 9, which left nothing for anyone Kalshi has not listed. The panel put 5% on exactly that, a probability you cannot buy; its tradable meaning is that the board as a whole is rich.

Why The Panel Doesn't Trust The National Polls

A national preference poll two years from a convention works like preseason ADP: it measures how often a name comes to mind, not how the race plays once voting starts. An early-state poll is closer to a projection, noisier but measuring the thing that decides outcomes first. The card handed to the panel carried both, and the two layers disagree hard.

Kamala Harris leads nearly every national poll in the card. In the two New Hampshire polls she prints 5 and 4, and the freshest Michigan poll has her at 5.1. Pete Buttigieg is the mirror image: he leads or co-leads every early-state print while sitting third or fourth nationally, and he is the only candidate in the card who has said, on August 3, that he leans toward running.

"That gap is the classic signature of residual name ID from a prior national campaign rather than durable primary-electorate strength." (Claude Opus)

Where The Machines Split From The Money

Pete Buttigieg: Market 5.45¢, AI Blend 15.8%

The widest panel-over-market gap on the board, and the most uniform: every seat landed between 14.5% and 17%.

"He is not merely polling nationally in the top tier, he leads both New Hampshire polls at 21% and 29%, leads the newer Michigan addendum at 24.2%, and has the only explicit recent intent signal in the card, saying on 2026-08-03 he is more inclined than not to run." (ChatGPT)

The caveat came from the seats that made him favorite. He holds no office, one unrated Michigan pollster drives part of his case, and, as Claude Opus put it, "small-state retail polling is exactly where he over-performed in 2020 without converting." That seat was also the lone holdout, keeping Newsom and Buttigieg level at 14.5 rather than following the rest of the panel onto a single favorite.

Jon Ossoff: Market 14.5¢, AI Blend 4.7%

The widest market-over-panel gap. Kalshi prices the Georgia senator as co-second-favorite; no seat gave him more than 6.5%. The panel saw the same rise the market sees but discounted it: his Senate term ends in January 2027, so a re-election campaign sits between him and any 2028 launch. The market is paying for the surge now; the panel wants November's result first.

Alexandria Ocasio-Cortez: Market 14.5¢, AI Blend 9.0%

She owns the best New Hampshire prints on the board, 22 and 17, and the panel priced that. What capped her was structure: a House seat has historically been a thin launch pad for a nomination, and several seats applied the same discount to her early-state strength that they applied to Harris's national numbers.

Kamala Harris: Market 9.45¢, AI Blend 12.4%

The one name the panel priced meaningfully above the market. The seats discounted her national leads hard but mostly kept her above 10, on the logic that a candidate who still starts at 30 in unaided national recall keeps a real path if she runs.

Rahm Emanuel: Market 4.55¢, AI Blend 0.54%

The board's quietest trap. Kalshi pays the former Chicago mayor and ambassador the same price as Josh Shapiro, a sitting swing-state governor. No seat found a poll to support it: he prints between zero and 2 percent in the handful of national polls that offer him.

Which Cheap Names Does The Panel Like?

• Gretchen Whitmer (0.95¢, blend 3.3%): the cheapest sitting-governor contract on the board relative to the panel's number. One seat's summary: "zero bad prints and a swing-state governor's platform but no breakout poll yet." (Claude Sonnet)
• Andy Beshear (3.55¢, blend 3.2%): "a sitting two-term red-state governor who appears in nearly every national poll at 2-8.5%, the classic late-consolidation electability profile." (Kimi K3)
• Zohran Mamdani (0.25¢, blend 0.67%): "sitting mayor of New York City since 2026, the largest municipal platform in the country, absent from poll answer lists so his support is unmeasured rather than zero." (Kimi K3)
• James Talarico (1.65¢, blend 0.44%): "the card lists him as the 2026 Democratic Senate nominee in Texas; a November win would instantly make him a national figure before the 2028 cycle starts." (Kimi K3)

The Bottom Line

The market spreads its money across the famous names: Newsom, Ossoff and Ocasio-Cortez carried 45.5 cents between them on August 9. The panel, reading the same polls with the name-recognition layer stripped out, puts its favorite on the one candidate leading where nomination races are decided first. In a fantasy draft this is the ADP-versus-projection gap, and the panel has published its projection. The first re-rank comes with the November 3, 2026 midterms, when Ossoff's Georgia result and Talarico's Texas race grade the second tier; the summer 2028 convention grades the rest, in public, on the model verdict scoreboard.

Verdicts generated August 9, 2026, price-blind. Prices as of August 9, 2026, 19:52 UTC. Panel: seven of the panel's eight seats ran this board (ChatGPT, Claude Fable, Claude Opus, Claude Sonnet, GLM 5.2, Kimi K3, DeepSeek V4), each revising in an anonymized cross-read; the blend is the simple mean of the seven revised numbers. Every seat is graded against real market settlements on the public scoreboard, alongside the Stokastic Sims vs Kalshi ledger that grades our sports edges the same way.
